The team, led by Assistant Professor Hou Yi from NUS College of Design and Engineering (CDE) and Solar Energy Research Institute of Singapore (SERIS), engineered a cyanate-integrated perovskite solar cell, addressing key challenges faced by current multi-junction solar cell technologies. By successfully integrating cyanate into the perovskite structure, the team achieved unparalleled stability and efficiency, surpassing previous performance benchmarks.
Assistant Professor Hou remarked, "After 15 years of ongoing research in the field of perovskite-based solar cells, this work constitutes the first experimental evidence for the inclusion of cyanate into perovskites to boost stability and improve power conversion efficiency."
Published in Nature on March 4, 2024, the experimental process leading to this discovery sheds light on the potential of cyanate as a substitute for bromide in perovskite solar cells, resulting in enhanced energy range and efficiency.
Dr. Liu Shunchang, a Research Fellow in Asst. Prof. Hou's team, employed various analytical methods to confirm the successful integration of cyanate, demonstrating its viability as a halide substitute.
Notably, the newly engineered perovskite solar cells exhibited a higher voltage and reduced energy loss compared to conventional counterparts. Encouraged by these results, the NUS team further advanced their research by assembling a triple-junction perovskite/Si tandem solar cell, stacking a perovskite solar cell atop a silicon solar cell.
Despite the complexity of the triple-junction structure, the assembled solar cell remained stable and achieved a certified world-record efficiency of 27.1 percent, certified by an independent photovoltaic calibration laboratory.
Assistant Professor Hou emphasized the groundbreaking insights gained from this research, highlighting the potential for further advancements in perovskite-based triple junction solar technology.
Looking ahead, the NUS team aims to upscale the technology to larger modules while maintaining efficiency and stability. Future research will focus on innovations in the interfaces and composition of perovskite.
